In recent years, the incidence of laryngeal cancer has shown an upward trend, especially in Henan, Hebei, Fujian, Guangzhou and other regions, the main age of incidence is 40-70 years old, more men than women.
Therefore, such people always have difficulty swallowing, it is necessary to carry out laryngoscopy, laryngoscopy full name electronic nasopharyngoscopy, is one of the commonly used examination methods in otolaryngology surgery, but the examination process is complicated, it may be necessary to take foreign bodies, biopsy to understand the scope of lesions and swallowing function.
So, when you need to perform a laryngoscopy, let's take a look.
First, repeat sore throat for a long time
If there is repeated or prolonged sore swallowing, a foreign body sensation in the pharynx, a feeling of blockage in swallowing, and blood in sputum, a laryngoscopy should also be performed to determine whether it is a pharyngeal hemangioma, an epiglottal cyst, or hypopharyngeal carcinoma.
In particular, the early stage of hypopharyngeal cancer is not obvious, and when the patient has laryngeal discomfort, foreign body sensation, and blood in sputum, it is necessary to perform laryngoscopy immediately.
Second, being pierced by fish bones or stuck in the throat by bones
When eating normally, it may get stuck in the throat if you are not careful, such as grapes, beans, bones, fish bones, if the card is very deep and the foreign body shape is not normal, you need to perform laryngoscopy.
Patients need to pay attention not to eat or drink for 4 hours before the examination to prevent nausea, vomiting and food from entering the trachea during the laryngoscopy.
Third, hoarseness
Hoarseness due to any cause requires a laryngoscope to confirm the diagnosis, and once the examination finds vocal cord lesions, this examination method can understand the cause of the disease and determine the symptomatic treatment plan.
Fourth, vocal cord polyps or tumors
If a disease of the larynx, such as a polyp of the vocal cords, nodules of the vocal cords, or malignant tumors such as laryngeal and hypopharyngeal cancer, a laryngoscopy is required to determine the extent and size of the lesion.
In this case, it is easy to misdiagnose without laryngoscopy, especially in middle-aged and elderly patients.
Under what circumstances to do laryngoscopy, it has been clearly understood, at this time patients also need to pay attention to the matters that need to be paid attention to before and after the examination.
First, try to fast as much as possible
If a biopsy is performed, fasting should also be done as much as possible to prevent nausea and vomiting from throat irritation. Especially if the illness is severe, you should not eat after 22:00 the night before.
Second, understand the patient's medical history
Prior medical history, such as high blood pressure, heart disease, current physical condition, and laryngeal symptoms, should be asked prior to the throat examination to see if there are conditions that affect the examination and to determine whether the patient can be examined.
Third, other precautions
During the examination, the patient should also try to relax the psychological state as much as possible to prevent excessive tension from being unable to cooperate with the doctor's examination, which affects the accuracy of the examination results. After laryngoscopy, if there is a sore sensation in the throat, care for a period of time is of great importance.
According to the above introduction, laryngoscopy is the main way to confirm the diagnosis of pharyngitis, pharyngeal tumors and other uncomfortable symptoms, so that the disease can be more carefully and thoroughly understood.
However, there are two kinds of clinical laryngoscopy, one is an electronic laryngoscope, the other is a support laryngoscope, the current electronic laryngoscope is used more, mainly to determine foreign bodies in the throat, as well as other types of diseases, support laryngoscopy is very common in surgery, often used to determine malignant tumors. Therefore, the pertinence of different examination methods is different, and patients must pay more attention.
